[Dovecot] auth both system and virtual users

[Gerry Reno]

I've setup dovecot to auth both system and virtual users but it is refusing
to work.  It keeps saying user is not found.  Is there something more that I
need to set?


dovecot.conf:
============================================================================
=
 default_mail_env = maildir:/var/mail/%1.1u/%u/Maildir
 mail_extra_groups = mail
protocol imap {
}
protocol pop3 {
}
protocol lda {
  postmaster_address = postmaster at example.com
}
auth_verbose = yes
auth_debug = yes
auth_debug_passwords = yes
auth default {
  mechanisms = plain
  passdb passwd-file {
    args = /etc/dovecot.deny
    deny = yes
  }
  passdb passwd-file {
    args = /etc/imap.passwd
  }
  passdb pam {
  }
  userdb passwd {
  }
  user = root
}
dict {
}
plugin {
}
